| interface | ::com::sun::star::container::XNameAccess |
| allows to get list of child elements and to check if an element with a specified name exists in a storage. | |
| interface | ::com::sun::star::lang::XComponent |
| allows to control and track lifetime of the storage. | |
This interface extends the base XStorage interface.

allows to get readonly copy of a child encrypted stream with encryption data.
If storage does not allow any encryption this method will always throw com::sun::star::packages::NoEncryptionException.
The stream is open in readonly mode so the com::sun::star::io::XStream::getOutputStream() method will return an empty reference.
This method allows to specify encryption data for the child stream explicitly.
| sStreamName | the name of the substream that should be copied |
| aEncryptionData | this parameter allows to specify an encryption data for the stream, the encryption data must be correct, otherwise an exception will be thrown |
| com::sun::star::embed::InvalidStorageException | this storage is in invalid state for any reason |
| com::sun::star::lang::IllegalArgumentException | one of provided arguments is illegal |
| com::sun::star::packages::NoEncryptionException | the stream is not encrypted |
| com::sun::star::packages::WrongPasswordException | the provided encryption data is wrong |
| com::sun::star::io::IOException | in case of io errors during stream opening |
| com::sun::star::embed::StorageWrappedTargetException | wraps other exceptions |

allows to get access to a child encrypted stream with EncryptionData.
If storage does not allow any encryption this method will always throw com::sun::star::packages::NoEncryptionException.
In case the stream is open in readonly mode the com::sun::star::io::XStream::getOutputStream() method will return an empty reference.
| sStreamName | the name of the substream that should be open |
| nOpenMode | a mode the stream should be open in, can be a combination of ElementModes values |
| aEncryptionData | this parameter allows to specify an encryption data to decrypt the stream, the encryption data must be correct, otherwise an exception will be thrown |
| com::sun::star::embed::InvalidStorageException | this storage is in invalid state for any reason |
| com::sun::star::lang::IllegalArgumentException | one of provided arguments is illegal |
| com::sun::star::packages::NoEncryptionException | the stream is not encrypted |
| com::sun::star::packages::WrongPasswordException | the provided encryption data is wrong |
| com::sun::star::io::IOException | in case of io errors during stream opening |
| com::sun::star::embed::StorageWrappedTargetException | wraps other exceptions |
